Model-level reading

What changes the warranty calculation

The GMC Sierra 1500 file contains 11 model years and 4,608 submitted complaints. The middle year in this set has 412 reports, giving each annual count a model-specific reference point.

2015 has the largest complaint count in the current file at 712. That does not establish a defect rate because sales volume and vehicle age differ across years.

Engine replacement or major internal repair carries the highest midpoint parts estimate among the applicable repair categories at $7,000. I would check whether that system remains under factory coverage before pricing an extra contract.
